Why don’t I receive the SMS verification code when I purchase something on 5173?

If you have not received the verification code sent immediately, you can enter the "Customer Service Center" on the 5173 homepage - "Unbind Mobile Phone" and select the unbinding method to unbind. After unbinding, you can use the original mobile phone number or change the mobile phone number and then bind the account. You can enter "My 5173" - "Account Settings" - "Mobile Phone Binding Settings" and click "Bind Now for Free". After entering the mobile phone number, prompt question, and verification code you want to bind, click "Next". Your phone will receive a text message. Enter the SMS verification code to complete the binding.
